What are the main components of the walkie-talkie?

- Sep 21, 2018 -


shell


Professional machines generally use PC+ABS, which has very good performance. It has good gloss, is not easy to age and wear, and the product is sturdy and durable. Commercial machines often use engineering plastic ABS, which can be used in appearance, strength, wear resistance and aging. Very good to meet the requirements; button with silicone, wear-resistant, not easy to age, feel good; aluminum shell with lightweight material aluminum alloy ADC12, easy to form and follow-up.


Host


Generally includes face shell, PTT button, earphone and power jack, intercom housing plug, PCB assembly, LCD part, volume / switch button, coding knob, indicator light, MIC, etc.


The PTT button acts as a launch switch, typically on the side. The indicator light indicates the working status, usually at the top. There is also a volume/switch button and a coding knob (select channel) on the top of the radio. The LCD part visually displays the working status of the intercom. The PCB component is the core part of the walkie-talkie. The important components are on the PCB, and non-professionals are not allowed to disassemble. Most walkie-talkies require special shields, aluminum shells (fixed PCBs), etc. due to technical performance and drop resistance requirements. Professional machines also have waterproof requirements and the structure is more complicated. The battery is divided into Ni-Cd, Ni-MH battery and Li-ion battery, and the capacity is 600mAh, 900 mAh, 1100 mAh, 1300 mAh, 1500 mAh, 1700 mAh, 1800 mAh, 2000 mAh, 2200 mAh, 2400 mAh. Lithium batteries are expensive and still in the development stage. Ni-Cd and Ni-MH batteries are commonly used, and Ni-MH batteries are generally recommended for large-capacity batteries. The battery surface and the bottom case are ultrasonically welded and are firm and reliable. The belt clip function is to fix the walkie-talkie on the belt, and the belt clip can be removed for the convenience of the customer. The antenna is divided into two parts: an antenna jacket and an antenna core. The antenna jacket is made of high-performance TPU material, which is resistant to bending and aging. The antenna core is generally connected to the host by a threaded structure, which is easy to disassemble.
